CLIP FOR WIRE ROPEWAYS.

SPECIFICATION forming part of Letters Patent No. 431,476, dated July 1, 1890.

Application filed November 27, 1889. Serial No. 331,791. (No model.)

To all whom it may concern-.-

Be it known that I, BARTLETT MOINTIRE, a citizen of the United States, residing in the city and county of San Francisco, State of California, have invented an Improvement in- Clips for WVire Ropeways; and I hereby declare the following to be a full, clear, and exact description of the same.

My invention relates to that class of dero vices which are intended to be attached to or clamped upon a traveling wire rope, and to have attached to the other end a hanger for supporting a load, said devices being known as clips and forming part of a system of :5 transmission by wire ropeways.

My invention relates particularly to that class of these clips which are suitably formed at one end for engagement with the rope or cable and at the other end for connection with the hanger which supports the load.

My invention consists, essentially, in a joint or hinge of said clip, whereby I am enabled to use carrying sheaves or pulleys with deeper-grooved faces, over which my clip, by

2 5 reason of its joint, can pass without difficulty.

My invention also consist-s in a peculiar clamping-connection of the device with the rope or cable, all of which I shall hereinafter fully describe, and specifically point out in the claims.

The main object of my invention is to provide a clip which can be used with deeperfaced pulleys than those in ordinary use, and also to provide in this connection a simple and effective clamping mechanism.

Referring to the accompanying drawings for a more complete explanation of my invention, Figure l is a vertical longitudinal section of my clip. Fig. 2is aplan of the same. Fig. 3 is a side elevation showing it riding over one of the deep-grooved carrying sheaves or pulleys. Fig. 4c is a View showing a modification of the joint or hinge.

A is the body portion of the clip, having secured to its outer end or formed therewith, as here shown, the flexible leaf portion B, which bends upon itself to form the lap or loop I) by which the rope-is clamped, and said leaf thence extends over on top of the body portion, and

is guided and held thereon by a bolt C passing through an elongated slot 1) made in the upper portion of the leaf.

D is the shaft portion of the clip, consisting of a cylindrical bar, from which the hanger (represented by X in Fig. 3) is suspended. This shaft portion is connected with the body portion by a pivotal joint, as shown at cl, this being effected in any suitable manner, as by slotting the rear end of the body portion and fitting the end of the shaft portion in said slot and passing apivotpin through the parts, all as shown in plan in Fig. 2. The shaft portion is formed with a cam or eccentric: arm E, which curves upwardly over the top and has its point fitted in the end of the elongated slot b in the-flexible leaf and playing down in a suitable opening a in the body portion.

In Fig. 3 F is the cable which the loop or lap of the leaf B embraces and clamps, as

shown, and this cable is carried along on suitable supporting sheaves or pulleys G, which have usually a shallow-grooved face, as it is difficult to make the clips pass them; but in my case it will be seen that I am enabled to make 7 5 a very deep groovesheave and yet have the clip override it on account of the joint in the clip between the shaft portion and the body portion. This operation is shown plainly in Fig. 3, and is the primary object of the joint. 86 I do not confine myself to the joint as applied to this particular form of clip, as it is useful in precisely the same manner, as shown in Fig. 3, in other forms of clips, no matter what may be the character of their connection with the traveling rope or cable; because, independent of this connection, the clip itself acts at the joint to ride over the pulley or sheave; but in this particular clip the joint serves the second function of binding the clamping-leaf 90 upon the cable. This is accomplished by the cam or eccentric-arm E, which enters the slot of the leaf. The hanger, which is shown only in part in Fig. 3, is bent inwardly, so as to carry the load as nearly under the cable as may be to preserve the equilibrium. Now the tendency of this hanger so bent is to bear outwardly and thereby raise the shaft portion of the clip, from which it is hung, so as to cause the eccentric-arm E of said shaft porroo tion to bear down constantly in the slot of the leaf, and thereby to draw said leaf back so as to tighten its lap or loop on the cable. The arm E also serves as the means for necessarily limiting the movement of the two portions on their joint, so that while the load is being carried the shaft portion will extend out rigidly from the body portion. Where the arm E is not used, any suitable shoulder may be formed on the shaft portion to abut on the body portion and limit the hinge-joint.

I do not confine myself to making the joint or hinge directly in the clip itself, for it may be formed as shown in Fig. 4, wherein a distinct shaft portionsuch as D-is dispensed with, its place being supplied by the bent upper end a: of the hanger X, which is hinged to the clip in the same manner as the shaft D is in the ordinary clip, and is provided with a limiting-stop 00, serving the same purpose, as far as the limiting of the hinge is concerned, as the arm E. This Fig. 4: also shows that the operation of the hinge-joint is the same as in the other figures, enabling the clip to override the sheave.

' Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A clip for wire ropeways connected with the load-carrying part by a joint or hinge, whereby said clip is enabled to ride over the cable-carrying sheaves, substantially as herein described.

2. A clip for wire ropeways connected with the load-carrying part by a joint or hinge, whereby said clip is enabled to ride over the cable-carrying sheaves, said joint or hinge having a stop for limiting its movement, substantially as and for the purpose herein described.

3. A clip for wire ropeways, having a body portion to be connected with the traveling cable, a shaft portion from which the hanger is suspended, and a pivotal connection or joint between the body portion and the shaft portion, substantially as herein described.

4. A clip for wire ropeways, having a body portion to be connected with the traveling cable, a shaft portion from which the hanger is suspended, a pivotal connection or joint between the two portions, and a contact shoulder or arm for limiting the movement of the parts on their joint, substantially as and for the purpose herein described.

5. In a clip for wire ropeways, the combination of a ,body portion having a clamping device for engaging the traveling cable, a portion carrying the hanger and pivotally connected with the body portion, and means operated by the movement of the hanger-carrying portion on its joint for tightening the clamp of the body portion on the cable, substantially as herein described.

6. In a clip for wire ropeways, the combination of a body portion having a clamp for engaging the cable, a portion for suspending the hanger and pivotally connected with the body portion, and a cam or eccentric-arm on the hanger-suspending portion, operating by the movement of said portion on its j oint to tighten the clamp of the body portion on the cable, substantially as herein described.

7. In a clip for wire ropeways, the combination of a body portion having a flexible leaf connected or formed therewith and forming a loop or lap for engaging the cable, said leaf having a slot in its upper portion, the portion for suspending the hanger and pivotally conportion on its joint the leaf is pulled back and its loop or lap tightened on the cable, substantially as herein described.

8. A clip for wire ropeways consistingof the combination of the body portion having a flexible leaf forming a loop or lap for engaging the cable, said leaf having an elongated slot in its upper portion, the guide-bolt passing through said slot for holding the leaf in place, the shaft portion for suspending the hanger and pivotally connected in the end of the body portion, and the cam or eccentricarm of said shaft portion having its point fitting and playing in the end of the slotof the leaf, substantially as herein described.

In witness whereof I have hereunto set my hand.

, BARTLETT MOINTIRE.
